Image restoration consists in recovering a high quality image estimate based only on
observations. This is considered an ill-posed inverse problem, which implies non-unique
unstable solutions. Regularization methods allow ...

Understanding the spatial distribution of prostate cancer and how it changes according
to prostate specific antigen (PSA) values, Gleason score, and other clinical parameters may
help comprehend the disease and increase ...

Parallel parking, in general, is a moderate difficulty maneuver. Moreover, for inexperienced
drivers, it can be a stressful situation that can lead to errors such as stay far from
the sidewalk or damage another vehicle ...

The backscatter coefficient (BSC) is an intrinsic property that quantifies the amount of energy
that is reflected by a material as function of the ultrasound wave frequency. BSCs have been
proposed for decades for tissue ...

We proposed a novel inpainting method where we use a multi-scale approach to speed
up the well-known Markov Random Field (MRF) based inpainting method. MRF based
inpainting methods are slow when compared with other ...

We introduce a novel methodology for locally updating an existing 3D solid model of a complex monumental structure with the geometric information provided by a 3D mesh (point cloud) extracted from the digital survey of a ...

Many pathological conditions are closely related with an increase in tissue sti ness.
For many years, experts performed manual palpation in order to measure elasticity changes, however, this method can only be applied on ...

Chronic wounds are a major healthcare problem worldwide which mainly a ects geriatric
population and patients with limited mobility. In tropical countries, Cutaneous Leishmaniasis
(CL) is also a cause for chronic wounds, ...

The pathological states of biological tissue are often related in attenuation changes of itself. Thus,
information about attenuating properties of tissue is valuable for the physician and could be useful in
ultrasonic ...

The minimum variance (MV) beamformer is an adaptive beamforming method that has the potential
to enhance the resolution and contrast of ultrasound images. Although the sensitivity of the MV
beamformer to steering vector ...

The attenuation coefficient slope (ACS) has the potential to be used for tissue characterization and as
a diagnostic ultrasound tool, hence complementing B-mode images. The ACS can be valuable for estimation
of other ...

Breast cancer is one of the greatest problems of national and international public health, whose incidence
among women population shows an increasing trend. Nowadays there are several elastographic
techniques, which seek ...

Object recognition in videos is one of the main challenges in computer vision. Several methods have been proposed to achieve this task, such as background subtraction, temporal differencing, optical
flow, particle filtering ...
